FIGURE 1.

On the left (A), an example of heart geometry, elaborated from the Zygote Solid Heart model ¹⁵ : the Left Atrium (LA) and the Left Ventricle (LV) are filled up with oxygenated blood (in red), while the right atrium (RA) and the right ventricle (RV) are full of non‐oxygenated blood (in blue); the ventricular myocardial muscle is shown in transparency, while the atrial muscle—being very thin—is not depicted. On the right (B‐D), the same ventricular geometry depicted with a decreasing level of details; for the most detailed one (B) an inside zoom of the papillary muscles and trabeculae carneae is also shown
